Hi guys, we’re glad to announce that we have officially supported the option to edit the SQL definition of your Query Model
Previously, after creating the SQL model, you will be unable to edit its definition in the UI mode. Instead, you will have to switch to Code mode for that operation 
.
We have solved this issue by supporting Edit SQL option right in the UI Mode of your SQL/Query Model. Your life will be much easier now 
Hope that this will enhance your experience with Holistics. Cheers!
